摘要
本文分别针对微分方程数值求解和数值积分两类问题,讨论了一种常见的加速收敛方法-R ichardson外推及其推广,同时给出了一定的理论分析,对之进行了对比数值实验,验证了理论的正确性.
The accelerated method- Richardson extrapolate method and its generalization for numerical solution of differential equations and itergral are discussed in this paper, and some induction are derived, moreover .some numerical results are displayed,whlch verifies the correctness in theory.
